Description

Reporting method and user equipment for realizing MBMS business continuity

Technical field

The present invention relates to a Long Term Evolution (LTE) technology, and more particularly to a reporting method and user equipment for implementing the continuity of a Multimedia Broadcast Multicast Service (MBMS).

Background technique

With the rapid development of the Internet (Internet) and the popularity of large-screen multi-function mobile terminals, a large number of mobile data multimedia services and various high-bandwidth multimedia services such as video conferencing, television broadcasting, video on demand, advertising, online education, and interaction have emerged. Games, etc., this aspect meets the needs of mobile users for multiple services, and also brings new business growth points for mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, they have the characteristics of large data volume, long duration, and delay sensitivity.

In order to effectively utilize mobile network resources, 3rd Generation Partnership Project ( 3rd Generation

The Partnership Project (3GPP) proposes Multimedia Broadcast Multicast Service (MBMS), which is a technology for transmitting data from one data source to multiple target mobile terminals, implementing the network (including the core network and Access network) Sharing of resources increases the utilization of network resources (especially air interface resources). The MBMS service defined by 3GPP can not only realize plain text low-rate message class multicast and broadcast, but also realize high-speed multimedia service broadcast and multicast, and provide a variety of rich video, audio and multimedia services, which undoubtedly conforms to the future. The trend of mobile data development provides a better business prospect for the development of 3G.

According to the prior art, a user equipment (UE, or terminal) that receives an MBMS service may be in one of two states, one being an RRC (Radio Resource Control) connection state (RRC-CONNECTED, referred to as a connected state). ), the other is RRC idle state (RRC-IDLE, referred to as idle state). According to whether the UE establishes an RRC link with the network side, it can be determined whether the UE is in a connected state or in an idle state. Specifically, when the UE establishes an RRC link with the network side, the UE is in a connected state; otherwise, the UE does not establish an RRC link with the network side, and the UE is in an idle state. In the prior art, the UE in the connected state will retain the UE in the network side. The configuration and parameters of the column (for example, the context, etc.); and for the UE in the idle state, the network side retains relatively less information of the UE, and the specific content is the prior art, and details are not described herein again.

In the mobile process of the UE, the mobility of the idle state UE is implemented by using a cell selection or reselection procedure, and the mobility of the connected state UE is implemented by using a cell handover procedure. The UE handover process is performed by the UE auxiliary network side; in other words, the network side (eg, source eNB (evolved Node B)) plays a leading role in the handover decision and the target cell selection process; The reported measurement report and other related information serve as a reference for the source eNB in making handover decisions.

BRIEF abstract

FIG. 1 is a flowchart of a reporting method for implementing connectivity of an MBMS service according to the present invention. Preferred embodiment of the invention

When the MBMS service is not introduced, the source eNB does not consider the impact of the handover decision and the selection of the target cell on the continuity of the MBMS service received by the UE when performing the handover decision. When the MBMS service is introduced, this factor needs to be considered and implemented as much as possible. After the handover, the UE can still guarantee the reception of the MBMS service in the target cell, that is, the MBMS service continuity; in the existing solution, the following methods are generally used to implement: When the UE is in the RRC_Connected manner, the HO (HandOver) handover process is used to notify the eNB of the MBMS service reception status by using the UE reporting mode. Generally, the MBMS service reception status information is lbit; when the value is 0, the UE is indicated. If the value of the MBMS service is not received, it indicates that the UE is receiving the MBMS service. After the base station learns the MBMS service reception status information, when the HO (Handover) decision is made (that is, when the target cell is selected), refer to the Information, when possible, when the HO decision is made, the UE is switched to the same-frequency cell, thereby ensuring the continuity of the MBMS service received by the UE.

However, in the UE reporting scheme, no specific achievable method has been given.

In the prior art, the eNB UE according to the measurement configuration constantly measured, when the measurement result satisfies the UE sends a measurement report condition when Burgundy, UE transmit MEASUREMENT REPORT message ^(measurement report message) to the eNB, wherein the information comprises a measurement report; The eNB determines the radio channel environment in which the UE is located according to the measurement information in the MEASUREMENT REPORT message sent by the UE, and accordingly serves as a basis for whether to switch the UE. The present invention can carry the MBMS service reception status in the measurement report message.

As shown in FIG. 1, the present invention provides a reporting method for implementing MBMS service continuity, including:

The UE reports the multimedia broadcast multicast service reception status to the network side by using the MEASUREMENT REPORT message.

The network side may be an eNB or other device corresponding to the eNB.

The specific method is: the MBMS service receiving status information may be sent as a field in the MEASUREMENT REPORT message; specifically, an IE (Information Element) in the MEASUREMENT REPORT message is sent; further, the information unit It may be a new information unit in the MEASUREMENT REPORT message or a redefinition of the information unit in the original MEASUREMENT REPORT message; the detailed description is as follows (where the message content of the MEASUREMENT REPORT message is directly given as prior art);

The MBMS service reception status is sent as an IE in the MEASUREMENT REPORT message: Measurement Re ort message

Preferably, according to the prior art, the UE continuously performs measurement according to the measurement information configured by the eNB, and the UE will send a MEASUREMENT REPORT message including the measurement report to the eNB as long as the reporting threshold is reached; because the handover decision of the eNB has delay or hysteresis Therefore, it is constantly updated (because the channel conditions are constantly changing over time) MEASUREMENT REPORT message will also be sent to the eNB continuously (send condition is to reach the reporting threshold). Considering that the UE may send multiple MEASUREMENT REPORT messages to the eNB, the UE of the present invention may carry the MEASUREMENT REPORT message each time according to a preset policy. The MBMS service receives the status information, or carries the MBMS service reception status information in a part of the MEASUREMENT REPORT message. The policy may be: selecting one or more MEASUREMENT REPORT messages of the N times MEASUREMENT REPORT message to carry the MBMS service reception status information; that is, allowing the UE to select one or more of the N MEASUREMENT REPORT messages sent or All MEASUREMENT REPORT messages contain MBMS service reception status information, and N can be set as needed. For example, one MEASUREMENT REPORT message is selected for each of the three MEASUREMENT REPORT messages to carry the MBMS service reception status information. The invention is not limited thereto. The present invention provides a user equipment for implementing multimedia broadcast multicast service continuity, and the user equipment is configured to report multimedia broadcast multicast service reception status information to a network side by using a measurement report message.
